Steam powered train

A train, also known as a railway train, refers to a vehicle that travels on a railway track. It is usually composed of multiple cars and is one of the most important modern vehicles for humans. Trains are a classic example of human transportation using fossil energy. In 1804, the British mine technician Drevisk used the steam engine of Watt to build the world's first steam locomotive at a speed of 5 to 6 kilometers per hour. Because coal or firewood was used as fuel at that time, people called it "train" and it has been used ever since. On February 22, 1840, the first train in the world, which was actually on the track, was designed by Cornwall engineer Charlie Rivisick.

In 1781, the train pioneer George Stephenson was born into a British miners' family until the age of 18, and he was still an illiterate illiterate. He ignored the ridicule of others and sat in the classroom with his seven or eight-year-old children. In 1810, he began to manufacture steam locomotives. In 1817, when Stephenson decided that he presided over the construction of a railway line from Liverpool to Manchester, a steam locomotive was used to transport a railway line that was completely transported by steam engines. From then on, the train began to rush on the human history stage.

In 1814, a British mining technician named Devivisk first used the steam engine of Watt to create the world's first steam locomotive. This is a single-cylinder steam engine that can tow five cars, with a speed of 5 to 6 kilometers per hour, while the real steam locomotive, the train, was invented by Stevenson. This kind of car used to use coal or firewood as fuel, so people called it "train", the name has been used until now.

The first coal-fired steam locomotive that used coal-fired steam power had a big disadvantage. It was necessary to install coal and water facilities along the railway, and it took a lot of time to add coal and water to the locomotive. These are very uneconomical. At the end of the 19th century, many scientists turned to electric and fuel locomotives. The world's first steam train that was actually on the track was designed by Cornwall engineer Charlie Rivick. Its train has four power wheels. It was tested on February 22, 1840. When it was empty, it was 20 kilometers per hour. When the load was heavy, it was 8 kilometers per hour (equivalent to the speed at which people walked quickly).

In 1924, Germany, the United States, France and other countries successfully developed diesel diesel locomotives, which are widely used in the world. In 1941, Switzerland successfully developed a new type of fuel turbine, fueled by diesel. The utility model has the advantages of simple structure, small vibration and good running performance, and thus is widely adopted in industrial countries. Since the 1970s, countries have developed high-speed trains, such as the high-speed trains from Paris to Lyon, with a speed of 300 kilometers per hour. The high-speed trains from Tokyo to Morioka in Japan have reached more than 250 kilometers. People are still greedy and unsatisfied with such high-speed trains. France, Germany and other countries took the lead in developing maglev trains. China has also built the world's first commercial maglev train line in Shanghai. The train is suspended above the track and has a top speed of 400-500 kilometers per hour. However, it consumes a lot of energy and radiation and loses hundreds of millions of yuan annually.
